WHEEL Specification o ettevs Patent.

Application filed October 19, 1908. Serial No. 458,535.

To all 'whom "it may concer/fi:

Be it known that we, Fnnnnmon E. Banthe United States, residing at Lincoln, in the county of Lancaster, State 'of lleloraslta, have invented certain new and useful llm-4 provements in TWheels; and wedo hereby declare the following to bea full, clear, and exactdescript-ioii of the invention, such as will enable others skilled in the art to which it appertains to make and use the Asaine.

This invention relates t improvements in wheels, more particularly to wheels having resilient or yieldingr propertiesand adapted more particularly :tor use in connection with automobiles and like vehicles, lbut which may also be employed upon vehicles of various kinds, and has orpne of its objects to simplify and improve the lconstruction and increase the eiiiciency, durability and utility di: devices of this character.

Another object of the invention is to pro-A vide a vieldabie 'wheel which "may be ap# -i plied with eqn-al tacihty to the heaviest or lightest vehicles, and without structurel cnanges in the vehicles.

lilith these and other objects in jview, the invention consists generally in .an axle having spaced collars,V a wheel'having a hollow heb arranged between the collares vand a coiled spring within the hub of the whe-el and connected one end to the hiib ain the other end to the axle., i

The invention/'further consists Iin an 1 with spaced disks at theends having in wardly directed conical projections, a "wheel having a hollow hub located betr-few disks, and Aa coiled spring ornief. converging stripwhereby the inner whirl. ot the spring is. thegsma-lles'tfnnd attached to the axle between the conical projeciions, and the larger outer Whirloi the spring convThe invention A:turther consists in ci novel features ofconstrnetion as `lieen shown and described and thenv speci? pointed out in the claim, Vandv in ings illustrative of the 1preferred s ment of the invention2 igu're 1 is elevation of one wheels of the improved the detachable disk removed. e liig. l is sectional view on the line. 22 or Fig?) is a view of the spring plate heile-ixy i.

" The improved' device comprises an axlefl l having a threaded outer end 11. Formed upon the axle and spaced Jfrom thc threaded l end is a dish. 12, and bearing upon the outer i end ci" the axle next to the threaded end is another similar dish 13, the confronting laces of the disks i rected conical projections 14T-15, the disks i being spaced apart a distance equal to Athe thickness or" the hub of the wheel. The l wheel comprises a hollow hub 1G, a rim or telly 17, a tire SV and spokes 19, the tire, telly and spokes being of the usual form. The' hub .16 extends between the disks 12-13, and is aboutv equal in diameter to the disks, as shown-, The hub 16 isllined with a metal cylindrical member 20, which is preterab y rigidly* anysuitable manner.'` y

connected thereto in the disl 'h of the y withv eis, as the 'springs within the hubs formed with inwardly diand to wheels yieldableupon vehicles of various'forms. What is claimed, is z* In a device-of the class described, a wheel comprising a hollow hub, a rim, and a plurality of connecting spokes, spaced disks between which said hub'is located, each of said disks having an inwardlyV directed annular conical projection, an axle extending through said disks, a sleeve surrounding said axle between said disks, and a coiled sprin smallest at the inner whirl and connecte by said smaller inner whirl to the sleeve -between the conical projections and by the outer Whirls to the hub, and against whose edges said conical projections bear.

In testimony whereof, We afi'ix our signatures in presence of two Witnesses.

and leads by its discharge 29 through the to wheels of various sizes, lining member 20, so that lubricating material may be supplied to the spring,'to preveilt oxidation. ,v

The various Whirls of the springwill be provided V'with small registering apertures 27 opposite the discharge of the oil cup, so that the oil will freely tlow to the axle.

The conical projections 14`15 serve an important function, as they el'ectually support the Whirls of the spring when the latter are fully compressed or condensed, and thus effectually prevent looseness or movement between the wheels and the axle, as the various whirls of -the spring receive the endwise thrust and absorb it so that it is not conimunicated to the axle through the impact ofthe hub members with the disks 12-18. This is an' important feature of the inven- FREDERICK E. ERTRAND tion and adds materially to its novelty and f i efficiency' GEORGE POBIXSCHE.

The cost of construction of the improved Witnesses:

wheel is not .increased materially and the L. C. Snx'roN, improvement may be applied, as above noted,
